Summary: The search for sustainable plastics is driven by the environmental pollution issues associated with petrochemical-derived plastics. Bioplastics, such as poly(lactic acid) (PLA), are increasingly being used in packaging due to limited fuel resources. However, poor ductility and gas barrier characteristics limit the use of PLA as food packaging material. This study aims to overcome these limitations by fabricating PLA/polyethylenimine-modified mesoporous silica (PEI-MS) composites. The influence of PEI content in MS and wt % loadings of optimized PEI content in MS on the properties of PLA is investigated in detail. The results show that PEI-MS modification improves the thermal stability and mechanical properties of PLA.

Summary: In this study, mixed matrix membranes (MMMs) containing pyrazole modified MCM-41 mesoporous silica (MP) as a nano-filler were prepared to improve the gas separation performance. The MCM-41-based MMMs showed a trade-off between permeability and selectivity. The PSf-MP membrane with the highest nanofiller loading (30 wt%) exhibited significantly improved permeability and selectivity for CO2/CH4 and CO2/N2, indicating the potential of these membranes for industrial gas separation applications.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
